Compared to 2D monolayers, osteoblasts grown in the 3D chip environment displayed differential mostly higher gene expression for osteocalcin, osteonectin, and alkaline phosphatase, while collagen type I remained fairly constant in both culture environments.
A more complex picture was observed for genes related to mitochondrial function with a mixed pattern of mostly downregulated gene expression in both female and male PD.
A subgroup of eight drug abuse cases displayed markedly different, and mostly opposite, gene expression changes which appeared to reflect distinct differences in lifetime drug abuse histories, toxicology and other medical conditions.
The first microarray analyses of the late 1990s (Eisen et al., 1998) considered mostly static gene expression profiles.
These results show that antigen-induced tolerance is an active process that upregulates a variety of genes instead of a process that mostly downregulates gene expression (Table 3).
Based on this study, HdIV affected transcript levels in both hemocytes and fat body, whereas MdBV mostly affected gene expression in the fat body.
As our data come mostly from gene expression analyses, further biochemical experiments are needed to identify the exact role of Manf in UPR.
This analysis suggests that human HKG functions, mostly involving gene expression, are functionally conserved in model organisms such as worm and yeast, while many human TEG-related functions were acquired after the divergence between humans and lower organisms.
The microarray analysis further revealed that acute METH also caused increased expression of 60 of 86 genes in saline-pretreated rats whereas there was mostly decreased gene expression (53 of 71 genes) after an acute METH injection to METH-pretreated rats.
Similar observations were previously reported in several Kras D12 transgenic models (Langenau et al., 2007; Sweet-Cordero et al., 2005), suggesting that the genes that are downregulated by Ras might be different between species and that Ras mostly upregulates gene expression.
